Riffle (anonymity network)

From Wikipedia, the free encyclopedia

Riffle is an anonymity network developed by researchers at MIT and EPFL as a response to the problems of the Tor network.

Riffle employs a verifiable shuffle and a symmetric-key algorithm.[1][2] Like Tor, it utilizes onion routing.[3] According to MIT's Larry Hardesty, researchers at MIT and the Qatar Computing Research Institute demonstrated a vulnerability in Tor's design.[4]

Messages sent over Riffle are not forwarded if they have been altered by a compromised server. The server has to attach proof in order to forward the message.[5]

The main intended use-case is anonymous file sharing. According to the lead project researcher, Riffle is intended to be complementary to Tor, not a replacement.[6]
